Oysters in deep trouble: Is Pacific Ocean's chemistry killing sea life?

Oyster larvae have been dying by the billions. Scientists suspect it's a sign that carbon dioxide is dramatically affecting the ocean

as the oyster industry heads into the fifth summer of its most unnerving crisis in decades, scientists are pondering a disturbing theory. They suspect water that rises from deep in the Pacific Ocean — icy seawater that surges into Willapa Bay and gets pumped into seaside hatcheries — may be corrosive enough to kill baby oysters.

If true, that could mean shifts in ocean chemistry associated with carbon-dioxide emissions from fossil fuels may be ... Full Story »

We should note that bivalves are a bellweather spieces whether native or not and while there can be speculation as to why they are declining, there is no escaping the fact that they are declining.

while no one has been able to prove definetivly that there is one cause to the decline of shellfish, it is important theat we look at all the possible causes as we take action. It should not be lost thst this is not a native spieces and as such, there is probably a reason that it was not there to begin with.

More science would fill in the story, but what is here is compelling news and opinions of oyster harvesters.

Climate change and ocean acidification combine to dictate conversion to solar power and multiplying efforts at human population control.

Indications that ocean acidification may already play a role in the decline of oysters are a “sign of things being out of balance, and that scares the living ... More »

Excellent heads up as to our further destruction of the oceans and their resources.

The alkalinity of a hatchery can easily be adjusted with slaked lime metered into the intake water but not much to do at a local level for the ocean or a bay. What a shame that we have probably destroyed yet another bounty that nature gives us for free in our race for ever growing economies.

Indicator species all over the planet from oysters to chemically sensitive humans point to huge problems with every natural system upon which life depends. These types of stories and a call for action are more important than endless debates about political systems.

Yes. No conclusions are reached & the reader is left to decide on the evidence that is presented. While there is a question mark following the title, & the tone is not one of emergency, the message is aptly conveyed that this is one more in a long series of effects that needs to be taken seriously & watched very, very closely, with authentic scientific evaluation.

This particular change apparently isn't as well studied as hundreds of other effects of a similar nature. But the fact that we have had a major impact (all negative) on the oceans is irrefutable. You can argue with science but you can also make a fool of yourself. It is much easier to destabilize the planetary systems than anyone has imagined.
